I get the following error when I run qplot()
qplot(grade, read,data = hhm.long.m, geom = c("point", "smooth"))
Error in smooth.construct.cr.smooth.spec(object, data, knots) :
x has insufficient unique values to support 10 knots: reduce k.
I am not sure how to tackle this problem. When I take a subsample (<
1000) than I am able to run that function but with my sample of ~
40,000 qplot gives me that error. I have 6 grades.
Please cc me on reply.
